Message 312 - Posted: 15 Oct 2011 | 14:44:41 UTC

I've tried a (preliminary) German translation:

!! ACHTUNG !! WARNUNG !!

Wenn das Gerät an den USB-Port angeschlossen ist liegt auf der rechten Seite der Platine (zwischen den Markierungen R22 und R23 nach rechts) eine Gleichspannung von ~400V an die durchaus gefährlich für Ihre Gesundheit sein kann.

Die rechte Hälfte der Platine nicht anfassen, wenn sie benutzt wird!

Sobald der Spannungswandler in seinem Steckplatz steckt und der USB-Anschluss angeschlossen ist übernehmen Sie die volle Verantwortung für mögliche Stromschläge und/oder Verletzungen!

Von Kindern und Haustieren fernhalten!

Um den Sensor laufen zu lassen benötigen Sie:
- eine Kiste, um den Sensor und das Geiger-Müller-Zählrohr (GMZ) hinein zu tun
- 2 ca. 7-10 cm lange isolierte Drähte mit isolierten Krokodilklemmen
- Schraubendreher
- ASB-Kabel A<->B (wie zu Drucker oder Scanner)

Zu Ihrer Sicherheit wird der Sensor mit ausgebautem Spannungswandler ausgeliefert.
Um den Sensor betreiben zu können müssen Sie die Anzeige mit einem Schraubendreher lösen und ausbauen. Unter dem Display, in einem schwarzen Schwamm, ist der Regler des Spannungswandlers eingepackt. Er sollte so in den Steckplatz auf der rechten Seite gesteckt werden, dass ein kleiner Punkt (kreisförmige Vertiefung) auf dem Gehäuse des Wandlers auf der rechten Seite unten ist (mit der Bezeichnung IC3).
Dann das Display wieder montieren.

Der nächste Schritt ist der Anschluss des GMZ, das Teil des Strahlendetektors ist. Zwei Drähte, möglichst verschiedenfarbig gekennzeichnet, müssen mit dem blauen Schraubklemmen, die mit CON3 (und den Worten "GM-Tube") gekennzeichnet sind, verbunden werden. Das mit (+) gekennzeichnete Ende des GMZ muss mit einem der Krokodilklemmendraht an die Klemme mit der Markierung + angeschlossen werden, das ohne Kennzeichnung entsprechend mit dem anderen Drahtan das ohne Markierung.

Der Sensor sollte in eine nicht-leitende Kiste, möglichst durchsichtig (um das Display ablesen zu können) eingebaut werden. Das GMZ darf die Platine nicht berühren, und das Ganze sollte nicht in der Kiste hin und her klappern.

Schließen Sie das USB-Kabel an und denken Sie daran, danach nicht mehr die rechte Seite des Sensors zu berühren!


If you (or any other readers) finds anything wrong, please tell me ;)

I think your detector is illegal in most countries because the user is not protected from the high voltage. You really should design the PCB to fit into a plastic box. Boxes are cheap and they often come with mounts inside to screw the PCB to. It would take extra work to cut a hole for the USB port, the LCD and leads to the GM tube but you are taking a great risk of selling a dangerous, illegal product and going to court for killing someone. You could eliminate the LCD and have 1 less hole to cut.

You have put a warning on the front page but it's only in English and it might get pushed off the page if you add other news items. Therefore it is not an adequate warning. Also, when people read the warning they will not want to order a detector because to them it will sound very dangerous. Protect yourselves and your project. Put the detector in a box and remove the warning from the front page. On each box put a label that has an international symbol of high voltage inside. With each box send a warning printed on paper in as many languages as possible, even if the warning is translated by Babel Fish online translator. Then if somebody gets hurt you can at least say you tried to provide adequate warning.

Also, a box will make the detector look more professional which makes it easier to sell. A few euros added to the cost won't deter people from buying a professional looking product.

How high is the voltage?
IF I recall this device is powered by USB?

USB is 5V 500mA standard if I remember correctly for the high powered mode.

even at 50 Volt that's 50mA max, hardly lethal.

at 100 Volt you'd get 25mA which you would definately feel but again not lethal unless you put it temple to temple maybe.

I understand your concern about the voltage, and people being careless, or just plain stupid and getting popped.

on the court thing, in the USA, yes our laws coddle the ignorant, but them being in poland, not sure how bad their lawa are compared to ours.

He also have the protection of selling it as a 'kit'. IF they are not able to put it in a box up front, they could sell it as a 'kit' explain specifically that it is a kit, the user needs to 'assemble it' and the USER has the responsibility of protecting themselves from any potential voltages. Simply state that us the END USERs, are responsible for boxing it up.

At this point, if I want to box it, it's up to me, if I get shocked because I didn't its MY fault, I was warned. Granted now, the typical american tard might go running for a lawyer, but common sense should prevail.

I know several other companies that sell... products.... from overseas to the USA in kit form. This helps them get it past customs, and possibly avoid fees. I know some 'devices' that an american can easily buy from overseas that assembled are 'illegal' but disassembled are just fine.

Did you bother to read the warning on the front page? It's 400 VDC! Even at low amps that's enough to stop your heart.

Yes, a warning and a suggestion to box it helps but if the warning is not clearly visible in the user's language then it does not qualify as a warning, not in your country, not in my country, probably not in any country.

Also, they're trying to sell to the average person. The average person sees 400 volts and thinks "Why should I spend money on a device that seems rather dangerous to me when I don't even see an urgent need to have that device?" The average person doesn't know how to box up a 400 volt device properly. There's just too many unknowns in his mind. His first impression is going to be "I don't need that!" and he'll click through. When you want to sell something you want to make it appear as safe as possible and as convenient as possible. Telling people "this is dangerous unless you box it" is just bad salesmanship. Put it in a $2 box and THEN try to sell it.

Besides, if they kill someone in the US they could be extradited from Poland to the US to face charges. Why try and get around the law when for $2 you can be in compliance with the law?

We're not talking about people burning their balls, we're talking about people getting killed. That meets with disapproval in most countries.

Again, it would take $2 to make the detector very safe. THINK about it. Who in their right mind would think that a person's life isn't worth $2. THINK about that.

We're talking about a beta-testing detection kit, that enthusiastic nerds like us could order to broaden the test field.
I was gladly surprised that I didn't have to solder it by myself, but that most parts are ready-to-use, only a few assembly work needs to be done @home, one of this is to put it in a Tupperware box.

I was looking for the post where Krzysztof said something about the plans to sell the mass production kit cased, and that they were looking for a suitable casing, but perhaps it was in a chat.

The sensors were to be distributed as a self assembly kit in the form of PCB and parts separately. However we have delay so it has been assembled in 95% that you after a few simple steps could start measuring radiation.

However, it is still a kit and the end user should care about a box for it.

We are working on the another version of the sensor which fits into one of the existing box.

How many Volts will be on the krokodylki?
Will it be the 400VDC or less?
So will the krokodylki have to be isolated for that current or will normal ones like those here cut in half be sufficient:

Technische Daten (technical data)
Max. Spannung 35 V (max Voltage)
Kabellänge 540 mm (Cable length)
Leitungs-Querschnitt 0.5 mm² (Cable thickness)

We're talking about a device with lethal voltage exposed. The fact that it is for beta-testing is irrelevant and would not hold water in court. Also they've sold it to ANYBODY not just nerds, notice they make NO attempt to differentiate who they sell it to. Even if it is sold only to nerds, nerds don't know everything and the project members would be found negligent, in the event of injury/death, if they didn't provide adequate protection which they have not. The warning on the front page isn't adequate because it's in 1 language only and if you put other translations of the warning on the front page previous warnings will get pushed off the page. Inadequate warnings, no insulation -> guilty.

Hey, I'm not saying I will report this situation to the authorities. I simply point out all the reasons why this situation is not good for the project admins and the end users and why I would like to see a change. Krzysztof says future detectors will be in a case so my job is done though I will continue to refute any argument that the current situation is somehow acceptable. It isn't.

FWIW, there are many kits for sale that have even higher voltages kicking around: Guitar amps and hifi amps are two that spring to mind. I dare say valve ('tube', if you must) based ham radio kits are still available.

Their approach seems to be "If you don't know about high voltages, don't buy it as you may kill yourself".

As for this project, I'd say that 100% of the purchasers are 'enthusiasts' and as such will actually read the instructions and heed them. Producing the 'consumer' nicely-boxed version is going to be expensive. The company I run abandoned importing some perfectly safe products from the USA because the cost of gaining CE approval initially made it quite risky for a new venture. It all comes down to volumes and dilution of compliance costs.

Anyhow, you can buy Tasers, defibrillators (and all sort of other extremely hazardous stuff) online, no questions asked ;)

I can't see that this project has done any worse than any other group of enthusiasts, but I understand the concern of some people.

Looking forward to getting my kit. I already have a super-deluxe tupperware box waiting to safely engulf it :)

I bet they provide adequate warnings though. This project has not.

That's what you would say but you have absolutely NO proof that all purchasers are enthusiasts. And even if they were enthusiasts they likely won't see the warning because it's inadequate and they may not know the high voltage hazard exists. You can't make unfounded assumptions like that when dealing with people's lives.

Producing the 'consumer' nicely-boxed version is going to be expensive.


As I said earlier, a box for the detector is worth about $2. Go to Mouser, Digi-Key or any online electronics parts dealer and look for yourself if you don't believe me. And then THINK Al, for god's sake THINK... is $2 too much to pay for protection against lethal voltage?

Anyhow, you can buy Tasers, defibrillators (and all sort of other extremely hazardous stuff) online, no questions asked ;)


You're not THINKING Al. Those devices come with adequate warnings and adequate shielding to protect the user. The device sold here does not.

I can't see that this project has done any worse than any other group of enthusiasts, but I understand the concern of some people.


I know many enthusiast groups and none of them have put uninsulated lethal voltage in the hands of naive users and failed to warn them. So yes this project HAS done worse than a LOT of other projects. Anyway, what other groups have done is irrelevant so that argument won't hold any water in court. If someone dies because you neglected to shield them from high voltage AND neglected to warn them of the danger you are guilty of involuntary manslaughter or worse in my country, the US and many other countries.

Forget the calculations, I highly doubt that the HV supply used on sensor board could provide more than a couple of miliampers. The main risk could be the shock from touching the output capacitor leads, unfortunately it can provide lots of current for a very limited period of time. For safety, do not touch powered sensor with both hands, also do not touch the sensor and PC case at the same time. It is best to disconnect it, the HV goes away a couple of seconds after disconnecting from USB.

One is grounded, the other one is connected to HV supply via >10MOhms resistance. The current flow through this circuit is limited to less than 0,00004A.
I definitely wouldn't recommend touching it, because something may go wrong if there is any malfunction on the sensor board.

Other than that, this video shows what happens when you accidentaly touch it:

The device can not hurt anybody without user manipulation - there is no voltage converter in the socket - there is no 400VDC.
If somebody just connects device to the usb without reading the instructions will get 0 points for the WU because Geiger-Muller Tube won't have polarization voltage so there won't be pulses from it.

Could you maybe put a small amount of rubber silicone stuff over those output capacitor leads. Should not affect the circuit and keep accidentially prone people insulated from an accidential discharge.

While it looks safer to touch the GM tube (as in the video), I thought I would put some duct tape over the ends to help hold the clips on, cover any exposed metal and prevent and accidential short either by a person or some other item accidentially falling on it.

Even a thin plastic non conductive sheet could be attached or taped on the backside of the circuit, protecting the whole thing.

All it takes is a little common sense to solve this problem if it is even a problem.

Perhaps on the next batch the entire high voltage side will be insulated.

The sensor on the video is experimental (it's one of the first batch rebuilt to so called "v2" hardware specs), so there's no need to insulate the tube.

Again, the thing is being sold AS IS, if you are so very afraid of electrocution, then go out and buy the 2 dollar container YOURSELF. Tin Foil hats are extra.

Hell, use a liter coke bottle and tape it back together afterwards with the cord running out of the cap hole. Make a slit in the side of the bottle, slide the cord in and through the cap hole, then slide the board into the bottle, glue or tape the slit shut, rtv up the hole and presto, instant waterproof container.

Dragoth, with an avatar of what looks like bush and crossbones, it shows you are bed wetting panzy assed leftist moron.


ASScholtoen, you're obviously another one of those braindead, snot nosed, needle dick, repuglicans who still thinks there was WMD in Iraq just prior to the invasion.

You obviously know very little about electricity by your postings, yet try to pretend you know all.


My little toe knows more about electricity, liability and guilt than your entire party of repuglican retards will ever know.


For those who wish to be educated; .100 amps is generally what it takes to kill someone if it is held for a second or more. some folks go by the school of .050 amps. If this thing is a few orders of magnitude less .0004? was it, it's not going to hurt you anymore than a static charge from rubbing your feet on the carpet.

Maybe you better outlaw carpeting and low humidity you buffoon.


Maybe you better do what you and every piece of repuglican crap like you longs to do and take a long hard suck on my asshole :-)

To the designers of the device. There will be people who bitch about everything no matter what you do, they won't be happy. Most of them cried and left the US to go live in Canada to be with their half uncle cousins. You are doing a good job, keep it up. I can't wait to get my hands on one of these to try it out myself.


To the designers of the device: there will always be retarded Americans coming to this forum bitching about anybody who doesn't think like them (though their country is rated next to Somalia) and think that eveybody who lives in Canada came from their shithole of a country. Ignore them.

Hey ASScholton, get off your sister, it's your father's turn!!




I wish to say thank you for that post drago, you have just proven my point beyond a doubt and let the world see what type of person you truly are. Dragoth, is that a World of Warcraft name? If so, then that explains all of this. Maybe you can use your gamma detector to find WMD's and save the world eh? Wow, you are funny, I mean that in a good way, I needed a good laugh, and seeing how easy your strings are pulled, well... it's funny.

I do wish to post a warning to the makers of this device though. Dragoth is a type of person, in America we call a liberal idiot. Others would use words such as parasite, leech, freeloader, stuff like that. This is the type of individual that really has no individuality, is pretty much a sheep, and is not one of those types who are very well educated or can take care of themselves. His type relies mostly on the government, subsidies, and whatever hand outs they can grab from those who do support themselves for sustenance. This is the type of person who is always looking for a handout or a free ride. This is the exact type of person who will run in front of a bus then try to sue the bus company, pour hot coffee in their laps, and cry they didn't know it was hot, and try to sue. Anything for a handout or free ride. I bet drago also lives with his parents still, even though he is in his mid 30's.

Right now it appears that dragy smells a potential free ride here. He will scream loudly about the dangers of your device, pretend he got 'hurt' with it, then run to one of his lawyer friends and try to sue you bleating 'i told them so' all the way, trying to parasite off of your hard work and efforts, just like his type have been doing all their lives.

Most people who are employed and self sufficient would say, 2 bucks for a box is no big deal, i can handle that. To dragoth however, that 2 dollars is 2 hours on his knees in the bus station, 2 hours he can't be playing world of warcraft. To him it IS a huge deal, as we have seen by his multiple posts bemoaning the lack of one. Essentially, your lack of a provided box, means he has to get his stretched out again to afford one for the project.

I guess we should commend him for 'Taking one for the team'.

You're not laughing. You're a foaming at the mouth, rabid, brain dead repuglican ranter who thinks I'm wrong for doing exactly what you did first. No matter what you do you useless repuglican pricks ALWAYS prove what retarded hypocrites you are. On top of that you've proven you have no idea what a gamma radiation detector is for. Why don't you go be stupid somewhere else?

I do wish to post a warning to the makers of this device though. Dragoth is a type of person, in America we call a liberal idiot. Others would use words such as parasite, leech, freeloader, stuff like that.
What has his ranting to do with political affiliation?

Funny thing, without his avatar I would have called him an American, right-wing nut-case idiot, who likes to sue others for his own stupidity. Liberals are usually better educated and tend to think more than the populist blabbermouths of the tea-baggers.

Regarding the war criminal Bush: Of course he is that, starting an aggressive war based on fabricated lies, founding and maintaining torture dungeons, kidnapping innocent people and sending them to be tortured to other countries and so forth would be called war crimes, if done by Ahmadinejad, and right so. But the same is true for the neo-con warmongers, who bankrupted the USA.

But, we all are very far OT, the mods would be right to delete all these posts, starting from Ascholten up to and including this one.

The only thing you wish to do is make a total ass of yourself. You have been very successful.

Dragoth is a type of person, in America we call a liberal idiot. Others would use words such as parasite, leech, freeloader, stuff like that. This is the type of individual that really has no individuality, is pretty much a sheep, and is not one of those types who are very well educated or can take care of themselves. His type relies mostly on the government, subsidies, and whatever hand outs they can grab from those who do support themselves for sustenance. This is the type of person who is always looking for a handout or a free ride. This is the exact type of person who will run in front of a bus then try to sue the bus company, pour hot coffee in their laps, and cry they didn't know it was hot, and try to sue. Anything for a handout or free ride. I bet drago also lives with his parents still, even though he is in his mid 30's.

Right now it appears that dragy smells a potential free ride here. He will scream loudly about the dangers of your device, pretend he got 'hurt' with it, then run to one of his lawyer friends and try to sue you bleating 'i told them so' all the way, trying to parasite off of your hard work and efforts, just like his type have been doing all their lives.

Most people who are employed and self sufficient would say, 2 bucks for a box is no big deal, i can handle that.


So why don't you just say $2 for a box is no big deal and stop your foaming at the mouth? Hmmm? I'll tell you why... because you're a moron and intend to prove that fact beyond a shadow of a doubt

To dragoth however, that 2 dollars is 2 hours on his knees in the bus station, 2 hours he can't be playing world of warcraft. To him it IS a huge deal, as we have seen by his multiple posts bemoaning the lack of one. Essentially, your lack of a provided box, means he has to get his stretched out again to afford one for the project.

I guess we should commend him for 'Taking one for the team'.


Now you're claiming I complained about the cost of the box. When are you going to stop making things up? Oh, I forgot, you can't tell the truth because you're a deranged, retarded repuglican and have no respect for the truth. You're like Anne Coulter... whatever stupid psychotic thought springs into your addled single cell of a brain you write down.

As for your psychotic ramblings about my lifestyle, get a brain, everybody here knows you can't possibly know that much detail about me. Once again you've proven you're an absolute retard. Rant on nut job, I'm sure you have 1000 more stupid lines to prove how totally fragged your brain is.

As for your moronic claim that I plan to claim I was injured by the detector, that really proves what a nut case you are. From what I've said in this thread it's obvious I believe the device can be dangerous. YOU would be stupid enough to go to court and say that you knew the device was dangerous but used it anyway. You are a repuglican so you really would be that stupid. Not me. I'm a liberal so I'm not stupid enough to pull something like that.

BTW, retard, Polish people are mostly liberals. I bet they're really impressed with your foaming at the mouth rant about liberals being evil, uneducated, leeches and freeloaders. You are so smard. ROFLMAO!!

I was thinking about this today and I have a technical question.

It gets it's power from the USB port right?
Let's assume somehow a catastrophic failure occurs. What are the chances of the high voltage being shot back up the USB cable to the computer and causing damage?

Granted now if someone spills a drink on the thing, well yes, all bets are off, but lets say, a more 'normal' failure, if there is such a thing, how well isolated is the HV side from the low side?

A small pip to someone's finger won't do much harm, but a computer circuit now, normally running at 5 Volt, getting hit with 400, that could be another story.

Both sides share common ground, so they're not entirely isolated. However, most if not all hardware failures on the HV side will result either with shorting the HV to ground (which may damage the onboard 34063) or no high voltage at all.
On the revision 2 board USB is protected from short circuit on the sensor (could happen for example if 34063 gets damaged) by a 10 Ohm resistor in series with the +5V DC. It limits the current to 500mAmps.

I believe most of the drinks are poor conductors, unless you drink salt water or something like that. Any conducting liquid would probably cause overload on the HV side and a huge drop in voltage. I think that only a low resistance short directly from the secondary side to +5V or data lines on USB could potentially do some damage.

BTW to use the sensor safely on a expensive PC, I think that the bluetooh could be a workaround that not implies circuit modifications:

hardware required:
#2 USB Bluetooth Dongle Class 2 (2 * 4 euro)
#1 USB external power supply + usb cable "through"

Let me know if a "bluetooh bridge" can works, because could be the best to me, also to place the sensor in the best site to catch gamma rays avoiding tube damages.

Alesandro, it sounds like you want to use the bluetooth for communications. I do not see why this would not work if you can somehow convince the computer that the 'bluetooth' is USB data. If this is doable it actually is a really good idea because then the device could be placed several feet away from the computer and wireless linked into it without having a tether to bother with. I also see an easy power supply to make it totally portable via a SLA battery with a little converter like you plug into your cigarette lighter hooked to the battery for those who wish to further experiment. I wonder if there is a way even to tether it to a cell phone to send the data via a wireless card to really extend the range.

Lots of potential here.

TJM, so if you spilled a coke or pepsi or other 'beverage' on the thing you believe it would be a poor conductor? I would think that with all the sugar and crap in them and the phosporic acid in coke and citric acid in many of the others, it'd actually be a pretty good electrolyte.

Edit: I just played around a bit, using a fluke it was hard to get an ohm reading because the meter jumped around. A Hi Pot Tester showed almost no resistance really.

Using a volt meter now, and dissimilar metals, coke is a good electrolyte and it made a battery that depending on the metals .. I played with aluminum / copper / brass / steel / silver, you can get a bit over half a volt from it.

With current running through it now, I bet this would strip / screw up a board very quickly. If the board traces are copper, they will take a lot of damage fairly quickly.

Even if it didn't conduct electricity where it didn't belong, the soft drink would mess up the board. Beer now probably wouldn't so we need to ditch the soda's and drink beer for the benefit of the project here :D

Hmmmmm. How can we possibly solve these mind boggling problems?

Hey! I know... Has anybody thought about the project devs buying at bunch of plastic boxes (cheap in volumes) and mounting the circuit board in the box? Or would the additional $2 added to the cost and the professional look a box adds to the device discourage people from buying it? Would a box make the device look too darn intelligent/liberal?

(Suggest repuglican retards sleep on this suggestion before responding or risk proving they're still dumber than a bag full of smashed rectums.)

There is no GPS item in the sensor, the coordinates are given by the users voluntary. Up to now I can only see teammates of the project in the list, so they are probably given on the team forum to the admins.

All sensors are send together (in 2 days) but obviously first come to users in Poland (because of distance and no borders), so it's understable that in this table arrive first that machines.

Locations are given by users on their hosts preferences site. Simply when first WU come back from host and validate you get a map in host preferences to give your position. It's opt to you that you give us your exact position or street 500 yards/meters from you...

Exactly, look at the URL of our images and just change the host ID to yours.

The box, including cables and clips for the geiger tube, cost me about 5€ in the local electronics supplier. I had to saw out a slot for the display and the usb cable.
The box is a little large, the sensor could easily have fit into a smaller one, but I don't mind as it just has to sit on a shelf, not be portable.

Edit: Al, that's a very low average radiation you have, where is your sensor placed?

As I mentioned in another thread, I seem to have to lowest average of anyone so far.

The GRS is temporarily in a light plastic box in my workshop which is just blockwork with a uPVC/cement roof. It's on top of the host pc, and there are quite a few large metal objects nearby, which could be shielding it from radiation from some directions.

Once I've devised a 'better' method of attaching to the tube than croc clips I'll put it in a nicer box and move it around and see what effect it has. I have PCs upstairs and downstairs indoors that it could be attached to, but being a 50's built house it's all pretty solid walls, so I thought the lighter built workshop might be a better option.

I'll experiment when I have more time. Early days yet :)

Al.

Im not sure of the diameter or the length of the actual geiger type tube but maybe a holder like a set of fuse clips for the little glass fuses? or the larger cartridge fuses might work? Bolt the holder down and run the wires to it. The clips are easily found and should handle a good 600Volt if you use an industrial like cutler hammer, siemens, ABB etc. I think even the standard 125 volt ones for projects should handle the voltage the thing uses, and a piece of electrical tape has a dielectric strength that will easily shield any potential grounding to nearby metal.

Thanks Szopler. That's good to know because a fuseholder will hold the tube much tighter than alligator clips will and be much less prone to falling off if / when the box is moved about.

For Americans, im thinking you can find them at just about any radio shack or electronics / electrical supply place. The hardware store might even have them. Id be careful of automotive stores because those might not have the full 600v rating since they deal with 12VDC and not household currents.

There's always E bay too.

The voltage rating only matters if you actually use it to install the fuse.
In our case it's just a piece of metal, doesn't matter what's written on it.

Message 401 - Posted: 27 Oct 2011 | 21:20:51 UTC - in response to Message 400.

Actually TJM what I was thinking of was use it to hold the tube. Since the tube has up to 400 volts on it, you would want something that can handle this voltage without breaking down.

The holders do also come with a black plastic / phenolic backing on them as well, some with holes in the ends to screw them down onto something. Just thinking of keeping it from eventually eating it's way to somewhere it shouldn't be if the holder / plastic can not take that voltage.

The reason I said 600 Volt is because I think that is the standard for all stuff good to 125Volt, which is the most common in the US. Even the wiring in your house, although it carries 120 / 240 Volt, the insulation is good for 600 Volts. That is what I was aiming at, not that it HAD to be 600 volt insulation. Some of the clips that you can get cheaply, like at an automotive store, might only be rated to 100 Volt, since they typically only see about 12 VDC, which could eventually give you problems.

Unless I am mistaken, the metal ends of the tube, isn't this where the power hooks up to?

Thank you for your reply.

There is no such thing as voltage rating for a simple piece of metal.
The voltage rating on the fuses (and their sockets) comes from the minimum gap needed to prevent arc forming when high current flows and the fuse breaks down. The longer the gap, the higher the voltage rating.

It doesn't relate to the geiger tube in any way, as there is no risk of arc forming. Instead of looking at the voltage, try to find fuse sockets which are covered in non-corrosive metal, they'll be more reliable.

For the bare clip no, there is no voltage rating but many of them as I have mentioned before come as an assembly. Mounted on plastic or phenolic or some other substance. That does have a voltage rating.

I am having problems with posting a picture directly into my post here so I will provide a url of what I am talking about.

This isn't exactly what I am talking about but gives you an idea.

The voltage rating on the fuse IS for the fuse itself, you are correct, but the fuse holders also have a rating on them as well as to the maximum safe voltage they can handle. This picture I provided a link to, those are rated at 250Volt it appears.

in this application, since you can get voltages up to 400 on the tube, these specific clips would not be suitable because eventually the voltage can break them down, and if they were mounted on metal, short out.

This 6 metal ends at CON2, that are covered with a sponge, what are they good for? Or better: What are we supposed to do with the sponge and the connector?

OK, I see.
I should have read the manual more carefully.
It simply should be removed, otherwise the detector is not working (as I have successfully done just now, with success meaning: detector doesn't work ;).
Once the sponge was removed it showed 0.04 - 0.10 µSv/h n my desk in front of the screen (TFT, perhaps I should try an old tube-type once ;)

Edit:
Here's a picture:

I've been told, that the picture is only to see if you are logged in to SETI-Germanys Forum, so here's it again, viewable for all.

As far as I can see pictures of our detectors on forums (here and at B@P) our volunteers are very creative persons ;)

That's pretty cool all the different ways people are figuring out to house their detectors.

We should set up a topic just for the purpose of people being able to show off their creativeness doing this.

Alesandro, it sounds like you want to use the bluetooth for communications. I do not see why this would not work if you can somehow convince the computer that the 'bluetooth' is USB data. If this is doable it actually is a really good idea because then the device could be placed several feet away from the computer and wireless linked into it without having a tether to bother with. I also see an easy power supply to make it totally portable via a SLA battery with a little converter like you plug into your cigarette lighter hooked to the battery for those who wish to further experiment. I wonder if there is a way even to tether it to a cell phone to send the data via a wireless card to really extend the range.

Lots of potential here.

Aaron

I'm not sure that this kind of bluetooth bridge will works, because it isn't between 2 PCs, but include a "slave" USB device (the sensor) that is not able to initialize the bluetooth pen.
If a init string from the sensor is enough configure the remote pen and to create the bridge, than a modify to the sensor firwmare would suffice. But I'm even not sure that the bluetooth hardware of the remote "true bluetooth devices" is symmetrical/identical to hardware of a bluetooth pen.

As there was one important line inserted after my tranlation, here's the updated version:

Da eine wichtige Zeile eingefügt wurde nach meiner Übersetzung, hier noch mal die korrigierte Version:


!! ACHTUNG !! WARNUNG !!

Wenn das Gerät an den USB-Port angeschlossen ist liegt auf der rechten Seite der Platine (zwischen den Markierungen R22 und R23 nach rechts) eine Gleichspannung von ~400V an die durchaus gefährlich für Ihre Gesundheit sein kann.

Die rechte Hälfte der Platine nicht anfassen, wenn sie benutzt wird!

Sobald der Spannungswandler in seinem Steckplatz steckt und der USB-Anschluss angeschlossen ist übernehmen Sie die volle Verantwortung für mögliche Stromschläge und/oder Verletzungen!

Von Kindern und Haustieren fernhalten!

Um den Sensor laufen zu lassen benötigen Sie:
- eine Kiste, um den Sensor und das Geiger-Müller-Zählrohr (GMZ) hinein zu tun
- 2 ca. 7-10 cm lange isolierte Drähte mit isolierten Krokodilklemmen
- Schraubendreher
- USB-Kabel A<->B (wie zu Drucker oder Scanner)

Zu Ihrer Sicherheit wird der Sensor mit ausgebautem Spannungswandler ausgeliefert.
Um den Sensor betreiben zu können müssen Sie die Anzeige mit einem Schraubendreher lösen und ausbauen. Unter dem Display, in einem schwarzen Schwamm, ist der Regler des Spannungswandlers eingepackt. Er sollte so in den Steckplatz auf der rechten Seite gesteckt werden, dass ein kleiner Punkt (kreisförmige Vertiefung) auf dem Gehäuse des Wandlers auf der rechten Seite unten ist (mit der Bezeichnung IC3).
Dann das Display wieder montieren.

Anschließend den kleinen schwarzen Schwamm an der Goldpin-Schnittstelle (CON2) entfernen.

Der nächste Schritt ist der Anschluss des GMZ, das Teil des Strahlendetektors ist. Zwei Drähte, möglichst verschiedenfarbig gekennzeichnet, müssen mit dem blauen Schraubklemmen, die mit CON3 (und den Worten "GM-Tube") gekennzeichnet sind, verbunden werden. Das mit (+) gekennzeichnete Ende des GMZ muss mit einem der Krokodilklemmendraht an die Klemme mit der Markierung + angeschlossen werden, das ohne Kennzeichnung entsprechend mit dem anderen Drahtan das ohne Markierung.

Der Sensor sollte in eine nicht-leitende Kiste, möglichst durchsichtig (um das Display ablesen zu können) eingebaut werden. Das GMZ darf die Platine nicht berühren, und das Ganze sollte nicht in der Kiste hin und her klappern.

Schließen Sie das USB-Kabel an und denken Sie daran, danach nicht mehr die rechte Seite des Sensors zu berühren!



If you (or any other readers) finds anything wrong, please tell me ;)

As the current detectors are no longer to assemble at home, perhaps you should unstickify this thread ;)
